26
Q

What is structure 14?

A

Bicuspid/Mitrial Valve

27
Q

Where do the electrical impulses start?

A

In the Sinoatrial node.

28
Q

Where do Electrical impulses go after they reach the sinoatrial node?

A

Atrioventricular node

29
Q

Where do the impulses pause?

A

At the atrioventricular node.

30
Q

The bundles of His are located where?

A

Introventricular septum

31
Q

What is the subendocardial conducting network made of?

A

Purkinje fibers

32
Q

What is structure 6?

A

P wave

33
Q

What is interval 4?

A

QRS Complex

34
Q

What is structure 9?

A

T wave

35
Q

What happens before the P wave?

A

SA node generates impulse, atrial depolarization begins.

36
Q

What happens on the P wave?

A

Impulse is delayed at the AV node. Atrial depolarization complete.

37
Q

What happens during the Q wave?

A

Impulse passes to apex, ventricular depolarization begins.

38
Q

What happens during the QRS complex?

A

Ventricular depolarization complete, impulse continues into Purkinje fibers.

39
Q

What is an ECG?

A

An ECG shows a record of voltage and time through the heart. It shows the electrical impulse through the non-contractile cells.
